Abstract

Using smaller CMOS nodes for the design of backplanes for light modulator enables the integration of additional features. This paper reports on a backplane designed in 28nm technology which embeds a complete framebuffer as well as a programmable high speed data interface which can realize up to 576Gbit/s data transfer rate to pixel array utilizing a 1440 x 1080 resolution with a 2.5 micron pixel capable for LCOS, OLED and micro-LED front planes. The programmable modulation scheme will be discussed in detail using typical scanning examples.
